Description
Technical field
The utility model relates generally to earthing clamp technical field, refers in particular to a kind of enclosed type wired earth wire clamp.
Background technology
Earthing clamp is a kind of electric power safety instrument for mounting short-circuit grounding wire, when carrying out interruption maintenance to high-tension apparatus or carrying out other work, short-circuit grounding wire can prevent equipment to send a telegram here suddenly produced dangerous voltage and electric arc, or prevent contiguous high voltage alive equipment and circuit from producing induced voltage to the harm of human body, also can in order to drain the residual charge of power cutoff device and circuit, personnel are avoided to get an electric shock and die or third-degree burn, to ensure the personal safety of operating personnel.And domestic used wire end earthing clamp mostly is the flat folder of outer image duck mouth formula at present, front opening is larger, when wire clashes into this wire clamp limiting bracket and after making it be shifted, this wire clamp can be clamped in wire clamp groove by parallel for wire automatically, after service work terminates, directly pulling wire clamp connection just can so that this wire clamp departs from wire, its advantage is simple to operate, but in the practical working situation that tower head operating space is limited, tower head operating personnel pull, the phenomenon of touching wire clamp connecting line can occur unavoidably, and due to the design defect of this cable clamp structure, pull, touching wire clamp connecting line all probably causes this wire clamp to depart from wire, if cause this wire clamp to depart from wire, service work will be made to lose safeguard protection, very easily cause the massive losses of personnel and property, potential safety hazard has been buried to whole service work.
Summary of the invention
For overcoming the defect had in above-mentioned prior art, the purpose of this utility model is to provide a kind of enclosed type wired earth wire clamp, this wired earth wire clamp is except having simple, the easy to operate advantage of structure, also can prevent in maintenance process because operating personnel pulls, touches wire clamp connecting line and make wire clamp depart from wire, reliability is high, eliminates the potential safety hazard in service work.
For achieving the above object, the technical scheme that the utility model adopts is:
Enclosed type wired earth wire clamp, for clamping wires, this earthing clamp is connected with wire clamp connecting line, this earthing clamp also includes wire clamp support, train wheel bridge and lower plate, wire clamp support is provided with holding tank, train wheel bridge to be connected on wire clamp support by the first torque spring and corresponding described wire is provided with opening in tiger's jaw shape, and lower plate is connected on wire clamp support by the second torque spring, and train wheel bridge and lower plate lay respectively at the both sides bottom holding tank and arrange in opposite directions, wire clamp support is also provided with train wheel bridge spacer pin, lower plate spacer pin and train wheel bridge locking device, train wheel bridge locking device comprises the locking slide block being connected with locking spring, the other end of locking spring is connected with extension section, when this earthing clamp does not clamp described wire, train wheel bridge top press clamping plate spacer pin and opening towards with holding tank towards consistent, lower plate top pressure clamping plate spacer pin, when this earthing clamp clamps described wire, train wheel bridge leaves lower plate spacer pin and under one end is locked in locking slide block, now train wheel bridge opening is towards lower plate direction, lower plate leaves lower plate spacer pin and is positioned at below train wheel bridge, described wire clamp is held in the bottom of holding tank by train wheel bridge and lower plate.
Clamping plate support, train wheel bridge, lower plate and train wheel bridge locking system be arranged so that wire is locked on this enclosed type wired earth wire clamp: when above-mentioned enclosed type wired earth wire clamp is installed, holding tank is only needed to aim at wire to be held, lifting earthing clamp again enters in holding tank to make wire, namely wire can compress train wheel bridge, lower plate rotates to the bottom direction of holding tank, until train wheel bridge slips over after train wheel bridge locking system by locking, now wire arrives bottom holding tank, the opening of train wheel bridge is towards lower plate direction thus closed by the opening of holding tank, wire is tightly clamped in the opening of train wheel bridge by the twisting force of the second torque spring by lower plate, with realize wire to close be clamped in wire clamp support holding tank bottom in.In maintenance line work, because train wheel bridge is by locking, namely wire is locked in the bottom of holding tank, therefore colliding or pull wire clamp connecting line all can not make this earthing clamp depart from wire, ensure that the good earth of wire in work, reliability is high, eliminates the potential safety hazard in service work, and structure is simple, easy to operate.In addition, this earthing clamp is made to depart from the process also very simple and fast of wire: only to need to lift extension section, extension section drives locking system to return, the locking of train wheel bridge is opened, by the twisting force of the first torque spring, the second torque spring, train wheel bridge and lower plate all rotate until top is pressed onto train wheel bridge spacer pin, lower plate spacer pin respectively to holding tank opening direction, and now the locking of wire is opened, and continue lift extension section and this earthing clamp can be made to be dragged from wire.
Described wire clamp support comprises two substrates be parallel to each other, and is connected between two substrates by connecting bolt, and described train wheel bridge is located between two substrates, described lower plate be located at two substrates two outside.Due to the middle part of train wheel bridge online design folder support, and the both sides of lower plate online design folder support, thus there is very strong centering, more firm safety when train wheel bridge, lower plate clamping wires.
Described holding tank is U-shaped holding tank.Holding tank is designed to U-shaped and wire can be made fully to contact with the bottom of holding tank, connects better effects if.
The side of the cambered surface corresponding lead of described train wheel bridge opening is arranged, the cambered surface that the side described lower plate with corresponding lead is arranged.Side due to train wheel bridge, the equal corresponding lead of lower plate is provided with corresponding cambered surface, and thus when clamping wires, the contact-making surface of train wheel bridge, lower plate and wire is comparatively large, can because ensureing that contact is good.
On described wire clamp support, the openend of holding tank is connected with installing insulating rope, described extension section is connected with unblock insulating cord.When installing this earthing clamp, only needing lift installing insulating rope, at the end of service work, only needing lift to unlock insulating cord and earthing clamp can be made to depart from wire, using more convenient and quicker.
Compared with prior art, the beneficial effect that the utility model brings is:
1. when installing this earthing clamp, can wire be locked in earthing clamp, collide or pull wire clamp connecting line and this earthing clamp all can not be made to depart from wire, ensure that the good earth of wire in work, reliability is high, eliminates the potential safety hazard in service work;
2. structure is simple, and the mode that lift is installed and lift unlocks operates more convenient;
3. the side of train wheel bridge, the equal corresponding lead of lower plate is provided with corresponding cambered surface, and thus when clamping wires, the contact-making surface of train wheel bridge, lower plate and wire is comparatively large, can because ensureing that contact is good;
4. the middle part of train wheel bridge online design folder support, and the both sides of lower plate online design folder support, thus have very strong centering, more firm safety when train wheel bridge, lower plate clamping wires;
5. this earthing clamp is installed firmly, if be not in place, the train wheel bridge of this earthing clamp, lower plate elastic force can make earthing clamp automatically disengage wire, and range estimation is very directly perceived, there will not be and installs situation not in place, safety and reliability.
